Description

[Detailed description of the invention] (Field of industrial application) This invention applies pressure to dust-containing air and slams it against the surface of the stored liquid, causing it to infiltrate and form air droplets mixed with it, as well as forming a liquid curtain. This invention relates to a cleaning dust collector that removes dust from dust-containing air to produce clean air.

(Conventional technology) Conventionally, as a cleaning dust collector,
There is a technique disclosed in Japanese Utility Model Publication No. 48-23945.

This applies pressure to the dust-containing air and slams it against the water surface in the dust collector, and the pressurized water that merges with the dust-containing air rises from both the inside and outside sides of the horizontal annular plate and collides with it, turning into a spray and rising as clean air. It was something to evaporate.

(Problems to be Solved by the Invention) Although it is possible to produce clean air with such conventional techniques, it is not efficient in a small volume.

In other words, it is well known that the wider the area of the liquid curtain that cleans the dust-containing air, the slower the speed of the dust-containing air passing through the liquid curtain, and the higher the efficiency. However, there was a problem in that it was not possible to create a liquid curtain over a wide area in a small volume.

Therefore, the purpose of the present invention is to efficiently infiltrate dust-containing air in a small volume, that is, to create a droplet-mixed air containing a large amount of droplets, and to form a liquid curtain over a wide area, thereby improving dust collection efficiency. It is an object of the present invention to provide a cleaning dust collector with improved performance.

(Means for Solving the Problems) In order to solve these problems, according to this invention, an outer cylinder 2 with a bottom in which a liquid surface 3 is formed by the stored liquid, and a lid of the outer cylinder 2 are provided. an outer cylinder main body 1 formed of a clean air rising cylinder 12 disposed on the lid 11, a dust-containing air injection cylinder 4 whose upper portion slidably projects from the lid 11, and a clean air rising cylinder 12 disposed on the lid 11; A radiation guide wall 5 that communicates with the lower end of the press-fit tube 4 and is formed in a radial and bellows shape, a mixed air guide tube 6 that stands upward from the outer periphery of the guide wall 5, and is continuous with the upper end of the guide tube 6. The outward facing flange 13 and the guiding wall 5 are connected to the liquid level 3.

and a floating body 10 formed from a downward annular cylindrical plate 8 and an upward annular cylindrical plate 9 disposed between the brim plate 7 and the liquid surface 3. is provided.

In the above configuration, the upward annular cylindrical plate 9 can be arranged in multiple stages so as to be downwardly directed outward.

In this case, a multilayer liquid curtain can be formed and the device can be made smaller.

(effect) The above technical means works as follows.

The dust-containing air is pressurized by the dust-containing air injection tube 4 in the direction of arrow X.
1, the dust-containing air is dispersed radially from the lower end of the press-in cylinder 4 along the radiation guide wall 5, and the inner air space created by the bellows-shaped guide wall 5 is dispersed. The dust-laden air blows up in the direction of the arrow X3 from the bottom part R1... and at the same time, the dust-laden air presses the liquid level 3 in the direction of the arrow X2.
The liquid spurts in the direction of 3.

That is, the pressurized dust-containing air is subdivided into multiple areas from the inner cavity R1 and the outer cavity R2 formed in the radiation guiding wall 5, and blows up the stored liquid, so that the dust-containing air is mixed into the stored liquid. It acts so that more of the liquid can be infiltrated in a small volume, and the subsequent liquid curtain can be formed over a wide area, for example, in multiple layers and stages.

To explain the action in this embodiment, the arrow
As mentioned above, the dust-containing air that is injected in one direction infiltrates a larger area than the hollow portions R1 and R2 of the radiation guiding wall 5 and is subdivided into infiltration, so that it becomes mixed air containing many droplets. and erupts in the direction of arrow X3.
